System and method for RFID-based printed media reading activity data acquisition and analysis
View Patent ↗The subject invention provides a means of automatically detecting and recording a person's use of magazines, i.e. printed media exposure, for the purpose of market research. The present invention comprises one or more electrically conductive marker regions applied to certain specific locations on one or more magazine pages. In one general embodiment, the presence and relative separation of the marker regions are detected by a capacitive sensors and electronic device that stores, processes and communicates the data wirelessly to an external device. In another embodiment, a passive chip less tag is used to indirectly measure the change in conductivity of the conductive regions caused by prolonged exposure to air or light. Exemplary methods are described for acquiring readership and exposure data using the present invention.
